Police have arrested a second man in relation to the importation of methamphetamine concealed in a large shipment of Honey Bear House Beer.
The beer has been linked to the death of a 21-year-old man.
In a statement on Tuesday, Police said Auckland City's organised crime unit is continuing its investigation and arrested a 40-year-old man on Tuesday morning.
It comes after a 30-year-old man was charged with supplying methamphetamine on Thursday.
Detective Inspector Glenn Baldwin said the man's arrest follows a search warrant by police in Auckland on Tuesday morning.
"This follows an earlier search warrant two weeks ago at an address in Ryan Place, Manukau."
The 40-year-old is expected in the Auckland District Court on Tuesday on serious charges of possession of methamphetamine for supply and supplying methamphetamine.
And while police have made two arrests, Det Insp Baldwin said their investigation "is by no means not over yet".
"Our investigation continues to develop at pace, and we cannot rule out further arrests or charges as a result."
Det Insp Baldwin said a "significant" amount of further social harm has been prevented "given the large quantity of drugs" that have been stopped from being "distributed or sold in our communities".
"Police continue to analyse the significant quantity of methamphetamine that was seized from the Manukau address earlier this month and will provide further updates as the investigation allows."

Police are also investigating a man's death which may be linked to the beer laced with methamphetamine.
Aiden Sagala died in Auckland Hospital earlier this month. Det Insp Baldwin said it was established Sagala wasn't "involved in any way with the importation or distribution of beer cans containing methamphetamine".
He said it is still an active investigation and "our team is working to link further individuals to this shipment and hold them accountable."
Det Insp Baldwin said while a "large quantity" of the meth-laced beer has been seized, there is still a risk of some cans circulating in the community.
He added police believe the specific beer is not available for purchase in Aotearoa.
"At this point we have identified that part of the shipment contains liquid methamphetamine concealed inside cans, with the remainder containing beer."
Police are urging anyone who may still have one of these Honey Bear House Beer cans to"not drink it" and to contact police immediately by phoning 105 and quoting the file number 230310/6793.
"Consuming beer contaminated with methamphetamine may have serious or fatal medical consequences."
Police ask anyone that might have further information regarding the product to also contact Police on 105 or Crime Stoppers anonymously on 0800 555 111.
